DAVID ROUSSEAU, or New YORK, N. if.

ELECTRIC GAS-LIGHTING DEVICE.

SPECIFICATION forming part. of Letters Patent No. 400,492, dated April 2, 1889.

Application filed July 6 1838. Serial No. 279,176. (No model.)

To all whom, it may concern:

Be it known that I, DAVID ROUSSEAU, a citizen of the United States, residing in New York,

county of New York, and State of New York,-

. and other lighting devices where the act of ig` nition'is brought about by creating an electric spark in the vicinity of the gas; and to this end it consists,`tr'st, in a novel arrangement of partsadapted to turn on and light the gas at one act, said parts being so compactly arranged as to be concealed beneath an imitation candle or'shield; Second, it consists in details of construction hereinafter described, and par- .ticularly pointed out in tlie claims which follow this specification.

The invention will be fully understood by referring to the accompanying drawings, in which- Figure 1 is a side elevation of a well-known form of candle gas-burner, the candle-shield being partly broken away to Show my improved attachments. Fig. 2 is a vertical sectional view showing the apparatus entire, and Fig. 3 is a plan view as seen looking into the upper end of the candle attachment.

A is a gas-burner xed in the usual manner to the burner-pipe.

B is a conducting yoke or collar insulated from the burner-tip a, and carrying a fixed electrode, b, located in close proximity to the gas-jet.

c is a metallic wiping-electrode, which plays loosely through a hole in a fixed metallic collar, f, secured rigidly to the burner A. The lower end ofthis wiping-electrode is j ourn aled in a rotatable pulley, C, on one end of the gascock, the other end of which projects through the burner, and is held firmly in place by an adjustable split leaf-spring, s, taking behind a Shoulder or groove, as shown.

d d is a cord or chain attached at a point on the upper surface of pulley C, the inwardlyprojecting end of the wiping-electrode passing through said cord or chain, so as to hold it "firmly in position.,v 'Io the lower ends of the cord or chain d d are attached two rods, Z l',

extending to the exterior of the protecting candle-shieldD through holes in the sustaining collar or ornament h., as clearly shown in Figs. l and 2. To the lower end of these rods are two ornamental chain cords, e e', with knobs for manipulating them.

w is a conductor or wire running from one pole of the battery (not shown) to the stationary and insulated electrode b, the wiping-electrode being connected throughthe gas-pipe to earth in the usual manner to the other pole of the battery.

The operation iis as follows: Supposing the gas turned o and the apparatus in posit-ion shown in Fig. l, taking hold of the lower knob attached to Chain e and pulling downward, the pulley C is rotated to the left, and with it the gas-cock and the lower end of the wiping-electrode c. This turns on the gas, and at the same instant causes the wipingelectrode to be lifted up and swung about its pivotal bearing in the collar f, thereby bringing it into sliding or wiping Contact with the fixed velectrode b and producing a spark, at the same time carrying it over and down out of the llame in the reverse position from that shown in Fig. 1. On reversing the action by manipulating the cord e the gas may be turned off.

I am aware that it is old to unite an igniting device to the cock of a. gas-burner, so that by one action the gas is turned on andlighted, and that it is also old to provide gas burners or jets with imitation candle-shields in imitation of candles; but I believe it is new with me to so combine these features as to make a neat., simple, cheap, and eective apparatus, being both novel and useful.

I am also aware that it is old in gas-lighting devices to combine a fixed electrode with a vertically-sliding electrode and apparatus for operating the same by cord or chain, all of said parts being located inside of a protecting or concealing shield; but I am not aware that it is old to use an electric gas-lighter wherein the electrodes, their operating mechanism, andthe cock are all operatively connected and located inside a guard or shield which conceals and protects allof said parts.

What I do claim, and desire to Secure by Letters Patent of the United States, is-

I. In a gas-lighting device, a rotary cock IOO In a gas-lighting device, the combination of a fixed and a wiping electrode, the latter I5 being pivoted to the gas-cock and having a sliding fulcrum or bearing through a fixed yoke or collar, all of said parts being surrounded by a protecting or concealing shield, Substantially as described.

DAVID ROSSEAU.
